I am looking for a guide on how to change the gobo within Elation. I have looked at this laser and do not see where I can swap out the gobo physically. I need instructions on how to change the gobo out. Example: I want to take one gobo and make it where our company logo takes the place of it and we can place it on the floor or wall. Also, The sky effect... I am looking for a way to use the sky effect but it isn't one of the listed effects on the gobo listing. Can someone please help? Thanks!
